Describe the problem properly and file a PR. The PR will be assigned to
ipfilter maintainer. You should also try to turn ipfilter on, and disable
multithreaded network stack (debug.mpsafenet=0 in loader.conf). See what
happens, and add this info to PR, too.

If you need to get your box running ASAP, you should try pf or ipfw. But
don't forget to file a PR.
